SHOE HEEL.

Application filed August 12, 1926. Serial No. 128,766.

Many people wear down the treads of their shoe-heels more rapidly on one side than on the other, the tread on the shoe for the right foot usually wearing more on the right side and the tread on the shoe for the left foot usually wearing more on the left side, thereby inclining the shoes and rendering the ankles of the wearer more liable to sprain. Besides a poor appearance results. Wear can however be equalized by exchanging the treads from time to time. As treads are usually put on by cementing and nailing this is not an easy matter and shoes are usually taken to a shoe repairer for the work.

The object of this invention is to provide a tread member and means of attachment of such character that the wearer of the shoes can readily make the change. A furtherobject is to provide a form of tread member which will make a suitably close fit to the shoe-heel along the edges with matched surfaces without using cement and withouttrinnning after exchanging, and which will be firm and will not become displaced.

In the accompanying sheet of drawings which forms a part of this description,

Figure 1 is a perspective of the underside of a shoe with a heel-plate nailed to the shoeheel.

'Fig. 2 shows the tread member from theside which goes against the shoe-heel.

Fig. 3 shows the spring metal plate which is embedded in the tread member.

Fig. 4 shows the heel-plate from the underside.

Fig. 5 is a vertical section through the tread member and metal binding plate on the line IV-IV of Figs. 2 and 3.

Fig. 6 is a perspective of the key.

Fig. 7 is a perspective of the nut.

Attached to the underside of the shoehcel 10 of a shoe is a heel-plate 11 with upstanding lugs 12, 12, a stud screw 13 and a spring clip 14 which is adapted to engage a r key 15 and hold it against the shoe-heel. The

key is provided with a hole 16 for the more effective engagement by the clip. It is also provided with a turned over head 17 by which it can be taken hold of by the fingers and pulled out from under the clip when needed for use in exchanging heels. key has prongs 18, 18 for engagement with a nut 19 which has recesses 20, 20 to receive the prongs.

A tread-member 21, which may be conveniently of molded rubber has embedded therein a binding plate of spring sheet metal with radially disposed tongues 23, 23. These tongues are bent out of the plane of the sheet so as to impart to the plate a concave form when not confined. This plate has transverse slots 24, 24 corresponding to the lugs in the heel-plate but longer than the width of the lugs to permit of transverse adjustment. There is also a transverse slot 25 corresponding in position to the stud screw in the heel-plate. There are mortises 26, 26 in one side which extend down to the transverse slots in the binding plate, and a through mortise or slot 27 which exposes the slot for the stud screw.

downagainst the shoe-heel plate by the nuton the screw stud and firm binding is insured all around the visible edge with no open cracks.

On account of the wide variation in sizes of shoe-heels it is customary for shoe repairers to carry a few sizes or" treads but not undertaking to have an exact size for each possible tread. When a tread is to be attached, the next larger size on hand is selected and in attaching matched at the back and when attached trimmed to match at the sides. It may not be attached so that exactly the same amount will need to be trinnned from each side and the stud screw may be located a little off the center line laterally. On account of this and to enable the treads to be properly set when exchanged with their edges matching the edges of the shoe-heels the slots to permit of lateral adjustment are provided. g

A shallow recess 28 in the tread member .opens into its edge and provides spaee The for the key and the clip which retains'the key. 7 I claim:

In combination with a shoe-heel an ex 5 changeable tread member provided with a recess which opens into its breast edge for recelvlng a key, a metal bindlng plate em- ANDREW BONO.
